Also, after coldstart, the valve closes in the throttle body breaking this flow of coolant anyways, which isn't much different from just capping both ends off. But who knows, probably something in there I don't know about.

Do you have any info backing up that statement about the "valve" closing the coolant passage in the TB? As stated above, wouldn't the hot wax rod need a continous flow of warm/hot coolant to keep the fast idle cam disengaged?
I hope you're right though, I'd like to eliminate the hose I've got connecting the two nipples, since it gets in the way when working with the fuel system or ECU harness on top of the engine (I've already ripped it once with a spanner, getting half a quart of hot coolant sprayed all over the engine bay and in my eyes).

Well, I think I was wrong about the valve on the cold start. I don't really fully understand the innerworkings of the coldstart system; just one of those things that I haven't had much interest in learning more about. As far as capping off those lines, I had to pull off my UIM to swap in some new injectors, and I saw that I have a hose running from the coldstart nipple on the water pump to the back o the block. I guess it's just safter to run the hose like that, but I'd still liketo know why.

There is really no logical reason for it to be "safer." The housings have water passages all along their width and length offering a fluid tank for the entire "block" otherwise known as the "cooling jacket." There is no way that rear housing is isolated from the rest of the sandwhich using only an 8-10 mm hose to transport it's cooling medium to the thermostat housing (and TB if you still have it routed). That would be a completely lousy design.

Just a warning about those vacuum caps. This has happened to me and quite a few others as well. When the rubber caps are used to block off coolant lines (I did that when I did the AST elimination) the oxidation process is accelerated and the caps become hard and cracks in a few weeks (yes, a few weeks). You are guaranteed to have you coolant everywhere. And you'll have to take everything apart again just to get to that cap. Robinette's site has made specific mention of this and suggests using a short hose with a bolt clamped in at one end as an alternative solution.
Just thought I let you know, if you decided to block the line off anyway.

Basically, I'm just taking care of a few things over winter so I can hopefully have an uneventful 2004 and not miss any track events. So, vacuum lines, replace all IC couplers and clamps, replace all manifold gaskets (LIM gasket still to do), injectors cleaned and balanced, etc...
Just normal stuff people should look at having done every so often...

OK this is a old thread but I just looked under my Manifold and TB and all that crap is under there..... Excuse my noobness but is this the "rats nest" everyone refers to... I have a single turbo and yet I still have all these damn hoses ? And also if I do order the block off plates this does eliminate all these damn whatever this crap is.
